APPLICATIONS: Any system in which it is desired to change and reverse a varying pneumatic signal to an Output signal of the same or higher pressure (up to 4:1).

FEATURES: Pneumatic snap action No dead center Reverse Action

SUPPLY PRESSURE: 5 to 30 psig

VARIABLE PRESSURE (input signal): 0 - 10 psig minimum 0 - 30 psig maximum

VARIABLE PRESSURE SNAPPING RANGE: Depends on Supply Pressure Approximately 2 - 7 psig at 30 psig

OUTPUT PRESSURE: 0 psig or Supply Pressure

OPERATION: Assume Variable Pressure (Orange) is at a minimum and the Diaphragm Assembly in an up position. An increase in Variable Pressure (Orange) on the MAIN DIAPHRAGM sufficient to overcome load of the BOOSTER SPRING plus the force of Supply Gas Pressure (Violet) on the full area of the SNAPPER DIAPHRAGM, the Diaphragm Assembly starts to move down. The upper seat, which is the Supply Gas inlet (Violet to Yellow), closes first. The PILOT PLUG SPRING holds the upper ball against its seat while a further downward movement opens the lower seat which is the pressure vent (Yellow to Atmosphere). Decreasing Output Pressure (Yellow) accelerates the downward movement of the Diaphragm Assembly to produce a sudden opening of the pressure vent. In order to reverse the above action, Variable Pressure (Orange) must be reduced so that the downward force on the MAIN DIAPHRAGM is less than the upward force on the BOOSTER SPRING plus Supply Gas Pressure (Violet) acting on the difference in areas of the SNAPPER and DIFFERENTIAL DIAPHRAGMS. With upward movement of the Diaphragm Assembly the pressure vent (Yellow to Atmosphere) closes first. The PILOT PLUG SPRING holds the lower ball against its seat while a further upward movement of the Diaphragm Assembly opens the Supply Gas Pressure inlet (Violet to Yellow). As Output Pressure (Yellow) increases pressure across the DIFFERENTIAL DIAPHRAGM is reduced, loading the Diaphragm Assembly in an up direction. The accelerated upward movement of the Diaphragm Assembly produces a sud-den opening of the Supply Gas Pressure inlet (Violet to Yellow).

3 PG THROTTLE PILOTS

www.kimray.com

APPLICATIONS: Any system in which it is desired to multiply and volume boost a pneumatic signal to a large motor valve or similar equipment. Amplification of the input pneumatic signal is approximately 4:1.

FEATURES: Pneumatic throttle Direct action Field reversible (See 3 PS for snap action)


VARIABLE PRESSURE: 0 to 30 psig

OUTPUT PRESSURE: Snap - 0 psig or Supply Pressure Throttle - Variable (0 - 30 psig)

OPERATION (Described for Throttle Action): Variable Pressure (Orange) acting on the MAIN DIAPHRAGM is the actuating force of the pilot. The counteracting force is the Output Pressure (Yellow) acting on the DIFFERENTIAL DIAPHRAGM plus the BOOSTER SPRING. When Variable Pressure (Orange) is zero, the Diaphragm Assembly is held in an up position by the BOOSTER SPRING. As Variable Pressure (Orange) increases slightly to overcome the load of the BOOSTER SPRING, the Diaphragm Assembly moves down-ward to first close the upper seat which is the pressure vent (Yellow to Atmosphere). The lower seat, which is the Supply Gas inlet (Violet to Yellow), has not yet opened, so both seats are closed with the PILOT PLUG. If Variable Pressure (Orange) increases still further, the Supply Gas inlet (Violet to Yellow) opens to increases the Output Pressure (Yellow) only sufficiently to balance the added Variable Pressure (Orange) acting on the MAIN DIAPHRAGM. With the Diaphragm Assembly in a balanced position any increase or decrease in Variable Pressure (Orange) will produce a proportional change in Output Pressure (Yellow) by opening either the Supply Gas inlet or the Output Pressure vent to re-establish the balance. The 3 PG Pilot is actually a pressure multiplier and volume booster. Output pressure (Yellow) is approximately 4 times the Variable Pressure (Orange). Output Pressure (Yellow) accu-rately follows small changes in Variable Pressure (Orange) to properly position motor valves, etc. for throttling control. For Snap Service, the 3 PG Pilot operates as described for the 3 PS Pilot on Page 40.1.

3PGA THROTTLE PILOTS

www.kimray.com

APPLICATION: Any system in which it is necessary to volume boost a pneu-matic signal to a large motor valve or similar equipment. As a volume amplifier for controls with a small feed volume.

FEATURES: Volume boosts a pneumatic signal without a corresponding pressure boost (1:1 Output Pressure vs. Variable Pressure) Direct Action Pneumatic Throttle



OUTPUT PRESSURE: Variable, 2 to 30 psig

OPERATION (Described for Throttle Action): Variable Pressure (Orange) acting on the CONTROL DIAPHRAGM is the actuating force on the pilot. The coun-teracting force is the Output Pressure (Yellow) acting on the DIFFERENTIAL DIAPHRAGM. When Variable Pressure (Orange) is zero, the weight of the Diaphragm Assembly forces the upper seat, which is the pressure vent (Yellow to Atmosphere), closed. The lower seat, which is the Supply Gas inlet (Violet to Yellow), is slightly opened. This results in an approximate Output Pressure (Yellow) of 2 psig. If Variable Pressure (Orange) increases, the Supply Gas inlet (Violet to Yellow) opens to increase the Output Pressure (Yellow) only suf-ficiently to balance the added Variable Pressure (Orange) acting on the CONTROL DIAPHRAGM. With the Diaphragm Assembly in a balanced position, any increase or decrease in Variable Pressure (Orange) will produce a proportional change in Output Pressure (Yellow) by open-ing either the Supply Gas inlet (Violet to Yellow) or the Output Pressure vent (Yellow to Atmosphere) to re-establish the bal-ance. The 3 PGA Pilot is actually a volume booster. Output Pressure (Yellow) is approximately 1 to 1 of Variable Pressure (Orange). Output Pressure (Yellow) accurately follows small changes in Variable Pressure (Orange) to properly position motor valves, etc. for throttling control.

3 PGM MANUAL RESET PILOTS

www.kimray.com

APPLICATION: Any system where a 3 Way Valve is to be monitored and system supply is to be vented if a preset limit is exceeded.

FEATURES: Intermittent bleed pilot 3 Way Valving Manual reset Provides tattle-tell signal when preset limit is exceeded Rapid venting action Direct acting



OPERATION: Assume that the 3 Way Valve to be monitored is ON. When Supply Pressure (Violet) is connected, Ball 2 of the PILOT PLUG is against the lower seat and prevents Supply Pressure (Violet) from reaching the Output (Yellow). The Diaphragm Assembly is held in a UP position by the BOOSTER SPRING. The upper seat and Ball 1 of the PILOT PLUG are separated allowing the Output Pressure (Yellow) to be vented. When the Reset Lever is manually raised, the upper seat is closed and the lower seat is opened allowing the Output Pressure (Yellow) to increase. This increase is transferred to the MAIN DIAPHRAGM through the 3 Way Valve and holds the Diaphragm Assembly down allowing the Output Pressure (Yellow) to equalize with the Supply Pressure (Violet). The 3 PGM is now LOCKED on and the Output Pressure (Yellow) equals the Supply Pressure (Violet). If the Output Pressure (Yellow) is interrupted by the 3 Way Valve and the Main Diaphragm Pressure (Orange) is vented through the 3 Way Valve, the Diaphragm Assembly will be pushed up by the BOOSTER SPRING and the Output Pressure (Yellow) is vented through the upper seat of the 3 PGM. The 3 Way Valve must be reset to ON and then the Reset Lever of the 3 PGM must be manually raised to resume operation.

30 PGMR MANUAL RELAY PILOT

www.kimray.com

APPLICATION: Manually sends a control signal to open or close a valve using a palm button. Supply is blocked and control signal bled to vent when released.

FEATURES: Direct acting Mounting bolts for bracket mounting Controls a relatively high pressure (300 psig) with minimal manual effort.



OPERATION: Manually depressing the PALM BUTTON causes the DIAPHRAGM PLATE and SEAT ASSEMBLY to close the upper seat with Ball 1 of the PILOT PLUG. This blocks the vent, further movement opens the lower seat at Ball 2 of the PILOT PLUG and communicates Supply Pressure to the Output. Releasing the PALM BUTTON reverses the action and allows the PILOT PLUG SPRING to close the lower seat with Ball 2 removing the Supply Pressure from the Output. The BOOSTER SPRING then opens the seat at Ball 1, bleeding the Output Pressure through the vent.

APPLICATION: Any system in which it is desired to reverse and multiply a varying pneumatic signal.

FEATURES: Intermittent bleed pilot Reverse acting Throttle action Adjustable Steam Pressure


OUTPUT PRESSURE: 0 to 20 psig Adjustable Steam Pressure

VARIABLE PRESSURE (input signal): 0 to 12 psig 30 psig maximum

PRESSURE RATIO: (Orange to Yellow) 1.5:1

OPERATION: The PILOT SPRING loads the upper side of the Diaphragm Assembly and is opposed by the Variable Pressure (Orange) act-ing under the PILOT DIAPHRAGM and by the Output Pressure (Yellow). Assume the PILOT SPRING is compressed with the ADJUSTING SCREW set for a desired Variable Pressure (Orange). With the Variable Pressure (Orange) to low, the PILOT SPRING holds the Diaphragm Assembly down, closing the upper seat at Ball 1 (Yellow to Atmosphere) and opening the lower seat at Ball 2 (Violet to Yellow). As the Variable Pressure (Orange) increases to the set pressure, the Diaphragm Assembly moves upward against the PILOT SPRING to first close the lower seat at Ball 2 (Violet to Yellow) and then open the upper seat at Ball 1 (Yellow to Atmosphere). In this position the Supply Pressure (Violet) inlet is closed and the Output Pressure (Yellow) is vented to atmosphere. PILOT SPRING #86 is furnished as standard. A heavier spring (Part #692) can be furnished on special order, to raise the Variable Pressure (Orange) from 12 psig to 30 psig.

3 PGP PRESSURESTAT

www.kimray.com

APPLICATION: Direct firing of small steam generators by controlling flow of gas through the pilot to the burner. Approximate capacity of pilot is 360 SCFH with 15 psig supply pressure. Pressure control of larger steam generators by regulating flow of gas through a motor valve. Motor valves are shown and described in Sections E-2 and E-3.

FEATURES: Intermittent bleed pilot Reverse acting Throttle action Adjustable Steam Pressure


OUTPUT PRESSURE: 0 to 20 psig Adjustable Steam Pressure

STEAM PRESSURE: 15 psig maximum

STEAM TEMPERATURE: 250 F maximum

OPERATION: The PILOT SPRING loads the upper side of the Diaphragm Assembly and is opposed on the under side by the Steam Pressure (Orange) and the Output Pressure (Yellow). Assume the PILOT SPRING is compressed with the ADJUSTING SCREW set for a desired Steam Pressure (Orange). With the Steam Pressure (Orange) too low, the PILOT SPRING holds the Diaphragm Assembly down, closing the upper seat at Ball 1 (Yellow to Atmosphere) and opening the lower seat at Ball 2 (Violet to Yellow). As the Steam Pressure (Orange) increases to the set pressure, the Diaphragm Assembly moves upward against the PILOT SPRING to first close the lower seat at Ball 2 (Violet to Yellow) and then open the upper seat at Ball 1 (Yellow to Atmosphere). The 3 PGP PRESSURESTAT may be used to fire small steam generators directly by connecting the Output Pressure (Yellow) to the burner. For larger units the Output Pressure (Yellow) can be used to operate a diaphragm motor valve installed in the burner manifold piping. See Sections E-2 and E-3 for applicable motor valves.

APPLICATION: Any system where two temporay pressure signals are avail-able. One sighal to turn ON the pilot and one signal to turn OFF the pilot.

FEATURES: Bistable operation Temporary signal will turn ON or OFF Intermittent bleed pilot Semi-snap action



ON/OFF SIGNAL: 20 to 30 psig

OPERATION: Assume that when the Supply Pressure (Violet) is applied, the upper seat Ball 1 is closed and the lower seat Ball 2 is opened. Output Pressure (Yellow) is vented to atmosphere. Since Diaphragm 2 is larger than Diaphragm 1, the Diaphragm Assembly is held down and the Ouput Pressure (Yellow) remains vented to atmosphere. When an ON signal (Green) is applied to the Main Diaphragm, the Diaphragm Assembly is forced upward, closing the lower seat and opening the upper seat. When the Supply Pressure (Violet) equalizes with the Ouput Pressure (Yellow), the Supply Pressure on Diaphragm 1 then holds the Diaphragm Assembly in the up position and the ON signal (Green) can be removed. When an OFF signal (Red) is applied to the Main Diaphragm, the Diaphragm Assembly is forced downward, closing the upper seat and opening the lower seat. This vents the Output Pressure (Yellow to Atmosphere). The OFF signal (Red) can now be removed and the pilot will remain in the OFF position. IF the 3 PGB is ON when the Supply Pressure (Violet) is applied, an OFF signal applied to the Main Diaphragm will turn the 3 PGB OFF.

FEATURES: Intermittent bleed pilot 3 Way Valving Up to 300 psig supply 20 to 30 psig ON/OFF signal Direct acting




OPERATION: With the Variable Pressure (Orange) on the Main Diaphragm at a minimum, the Booster Spring lifts the Diaphragm Plate and Seat Assembly closing the lower seat Ball 2 and opening the upper seat Ball 1, venting the Output Pressure (Yellow to Atmosphere).With an increase in Variable Pressure (Orange) sufficient to overcome the Booster Spring, the Diaphragm Plate and Seat Assembly will be moved downward and the upper seat will be closed. As the Variable Pressure (Orange) continues to increase, the lower seat will be opened communicating Supply Pressure (Violet) to Output Pressure (Yellow). When the Variable Pressure (Orange) is decreased to a minimum, the Booster spring will raise the Diaphragm Plate and Seat Assembly, clos-ing the lower seat (Violet to Yellow) and opening the upper seat (Yellow to Atmosphere), reducing the Output Pressure (Yellow to Atmospheric Pressure).

3 PM MECHANICAL PILOT

www.kimray.com

APPLICATIONS: On oil and gas separators, water knockouts and similar equipment where motor valves are required. Where a pneumatic signal is desired from mechanicalmovements such as a float.

FEATURES: Direct float operated Snap or throttle action Field reversible Controls any motor valve requiring up to 30 psig diaphragm pressure.


OPERATION: Assume the Diaphragm Assembly is held in an up position by an outside float arm connected to the pilot LEVER with a turnbuckle. Such an arrangement is shown in the 3 PM installation photograph, lower right-hand corner. The BOOSTER SPRING together with Supply Pressure (Violet), acting on the difference in areas of the SNAPPER and DIFFERENTIAL DIAPHRAGMS, forces the Diaphragm Assembly against the LEVER. With a downward movement of the LEVER the upper seat, which is the pressure vent (Yellow to Atmosphere), closes first. The PILOT PLUG SPRING holds the upper ball against its seat while a further downward movement of the LEVER opens the Supply Pressure inlet (Violet to Yellow). As Output Pressure (Yellow) increases, pressure across the DIFFERENTIAL DIAPHRAGM is reduced, loading the DIAPHRAGM ASSEMBLY in a down direction. The accelerated downward movement of the DIAPHRAGM ASSEMBLY produces a sudden opening of the Supply Pressure inlet (Violet to Yellow). In order to reverse the above action, the upward force of the LEVER on the Diaphragm Assembly must be greater than the force of the BOOSTER SPRING plus Supply Pressure (Violet) acting on the full area of the SNAPPER DIAPHRAGM. As the Diaphragm Assembly moves up, the Supply Pressure inlet is closed first. The PILOT PLUG SPRING holds the lower ball against its seat while a further upward movement of the LEVER opens the pressure vent (Yellow to Atmosphere). Decreasing Output Pressure (Yellow) accelerates the upward movement of the Diaphragm Assembly to produce a sudden opening of the pressure vent. The sudden changes in Output Pressure (Yellow) caused by movements of the LEVER, snap actuates any motor valve to which it is connected. For throttling Service, connect Supply Pressure (Violet) to opening marked THROT on the pilot body. This will require changing the pivot on the LEVER or reversing the motor valve action. The supply gas connection for snap service becomes the exhaust for throttling service.

4 POR PRIORITY SIGNAL RELAY

www.kimray.com

APPLICATIONS: Shut-in relay Remote shut-in relay Signal priority sensor Automatic shut-down relay Signal interruption

SPECIFICATIONS: Connections - 1/4" N.P.T. Max. Body design pressure - 300 psig Max. Inlet pressure Port 1 - 40 psig Max. Inlet pressure Port 2 - 40 psig Max. Operating temperature - 150F. Pressure required at Port 2 to override the pressure at Port 1 20 psig or 70% of the pressure at Port 1 (whichever is greater).

MATERIALS: Body - Anodized aluminum Springs - Steel, (Zinc plated) Diaphragms - Buna-N Valve Element - 316 S.S. Valve Seats - 303 S.S. (Other material available on request)

OPERATION: Assume there is no pressure at Port 2 (see diagram 1). The BALLAST SPRING will raise the DIAPHRAGM ASSEMBLY, lift-ing Ball 1 and opening the LOWER VALVE. The LOAD SPRING will cause Ball 2 to close the UPPER VALVE. The Normal Signal (Yellow) at Port 3 will be the pressure at Port 1. The pressure at Port 1 can be a constant pressure or a variable pressure. When pressure is applied at Port 2 (See diagram 2), the DIAPHRAGM ASSEMBLY moves downward. This causes Ball 1 to close the LOWER VALVE. As the DIAPHRAGM ASSEMBLY continues to move down, it compresses the LOAD SPRING and unseats Ball 2 in the UPPER VALVE. This allows the Priority Signal (Violet) from Port 2 to be transmitted to Port 3, the Priority Signal (Violet) at Port 2 should be a pressure of 20 to 40 psig. When the Priority Signal (Violet) at Port 2 is reduced below 1 psig the relay will reset to the original position with Port 1 com-municated to Port 2.

Pilot may be used as a Pressure Reducing Regulator with a Pressure Opening Motor Valve.

OPERATION: The DIAPHRAGM ASSEMBLY and the Bellows Assembly are the only moving units in the pilot. The PILOT PLUG consist of two stainless balls rigidly connected together. The upper seat of the PILOT PLUG is the vent for the Modulated Output Pressure (Yellow to Atmosphere). The lower seat of the PILOT PLUG is the Supply Pressure inlet to the Modulated Output (Violet to Yellow). The SPRING in the bonnet loads the upper side of the DIAPHRAGM ASSEMBLY and is opposed at the opposite end by the BELLOWS STEM. The BELLOWS STEM is actuated by the Sense Pressure (Orange) acting on the outside of the BELLOWS. Assume the SPRING is compressed with the ADJUSTING SCREW for a set pressure greater than the Sense Pressure (Orange). The DIAPHRAGM ASSEMBLY is forced downward by the SPRING. The upper seat of the PILOT PLUG (Yellow to Atmosphere) is closed and the lower seat of the PILOT PLUG (Violet to Yellow) is opened. This allows Supply Pressure (Violet) to provide a Modulated Output Pressure (Yellow). As the Sense Pressure (Orange) increases to the set pres-sure, the BELLOWS begins to contract, moving the BELLOWS STEM upward against the DIAPHRAGM ASSEMBLY. This com-presses the SPRING and closes the lower seat (Violet to Yellow)

and opens the vent for the Modulated Output Pressure (Yellow) to decrease. The intermittent bleed, three-way valve action of the PILOT PLUG against its seat adjusts the Modulated Output Pressure (Yellow) in and the set pressure. The rapid but stable repositioning produces a true throttling action. The action of the pilot may be changed from Indirect to Direct by inverting the SUPPLY HOUSING and the DIAPHRAGM ASSEMBLY.

PRESSURE PILOTS

www.kimray.com

APPLICATION: Pilot may be installed remotely from the motor valve (see Motor Valves shown in Sections E1 and E2). This pilot is used in the regulation of inlet pressure to gas compressors, the control of supply pressure, or distribution system pressure. It may be used to produce a pneumatic output signal when the monitored pres-sure falls below the set pressure. The pneumatic signal source is isolated from the monitored pressure.

FEATURES: Single Adjustment Filtered gas supply Accurate control Intermittent bleed pilot construction Remote installation

SUPPLY PRESSURE: Equal to or not less than 60% of maximum upstream pres-sure when used to operate low pressure motor valves (shown in Section E2). 20 to 30 psig when used to operate high pressure motor valves (shown in Section E1).

PRESSURE RANGE: 5 psig to 300 psig.

OPERATION: The Pilot Assembly, which moves as a unit without friction within the housing, is supported by the PILOT DIAPHRAGM and the MODULATING DIAPHRAGM. The PILOT SPRING loads the upper side of the Pilot Assembly and is opposed on the underside by Controlled Pressure (Blue) acting on the net area of the PILOT and MODULATING DIAPHRAGMS (area of PILOT DIAPHRAGM minus area of MODULATING DIAPHRAGM). The 12/30 PG Pilot can be considered as an inverse multi-plier. Each 1 psig change in Controlled Pressure (Blue) results in a change in Output Pressure (Yellow) of 8 psig. A ratio of 8:1. With a slight decrease in Controlled Pressure (Blue) the Pilot Assembly is forced downward by the PILOT SPRING. The upper seat for the PILOT PLUG (Yellow to Atmosphere) is closed and the lower seat for the PILOT PLUG (Red to Yellow) is opened. This results in an increased Output Pressure (Yellow) under the MODULATING DIAPHRAGM which balances the lost upward force due to the slight decrease of Controlled Pressure (Blue). The Pilot Assembly returns to a position at which both the upper and lower seats are closed. A slight increase in Controlled Pressure (Blue) opens the upper seat and closes the lower seat to reduce the Output Pressure (Yellow).

HIGH PRESSURE - PRESSURE PILOTS

APPLICATION: The 30 HPG-D is used to produce a pneumatic output signal when the monitored pressure falls below the set pressure. The pneumatic source is isolated from the monitored pressure by a vent chamber which allows the monitored pressure to vent away if it reaches a high enough pressure to cause diaphragm failure. The control pilot may be remotely installed to operate a motor valve and function as a pressure reducing regulator. The best application of this pilot is for instrument protection where the monitored pressure may surge above the rated pres-sure of the pilot.


SUPPLY PRESSURE: Equal to or not less than 60% of maximum upstream pres-sure when used to operate low pressure motor valves (shown in Section E2). 20 to 30 psig when used to operate high pressure motor valves (shown in Section E1).

PRESSURE RANGE: 5 psig to 300 psig

OPERATION: The 30 HPG-D consists of a PILOT DIAPHRAGM ASSEMBLY which moves without friction within a housing, to operate a 3 way PILOT PLUG. PILOT DIAPHRAGM ASSEMBLY is sup-ported by the PILOT DIAPHRAGM and the MODULATING DIAPHRAGM. The PILOT SPRING loads the upper side of the PILOT DIAPHRAGM ASSEMBLY and is opposed on the underside by Controlled Pressure (Blue) acting on the net area of the PILOT and MODULATING DIAPHRAGMS (area of PILOT DIAPHRAGM minus area of MODULATING DIAPHRAGM). The 30 HPG-D can be considered as an inverse multiplier. Each 1 psig change in Controlled Pressure (Blue) results in a change in Output Pressure (Yellow) of 8 psig. A ratio of 8:1. Assume that the Controlled Pressure (Blue) is at the set point. With a decrease in Controlled Pressure (Blue) the PILOT DIAPHRAGM ASSEMBLY is forced downward by the PILOT SPRING. The upper seat for the PILOT PLUG (Yellow to Atmosphere) is closed and the lower seat for the PILOT PLUG (Violet to Yellow) is opened. This results in increased Output Pressure (Yellow) under the MODULATING DIAPHRAGM which balances the lost upward force due to the slight decrease of Controlled Pressure (Blue). The PILOT DIAPHRAGM ASSEMBLY returns to a position at which both the upper and lower seats are closed. A slight increase in Controlled Pressure (Blue) opens the upper seat and closes the lower seat to reduce the Output Pressure (Yellow).

PRESSURE DIFFERENTIAL PILOTS

www.kimray.com

APPLICATIONS: Pilot may be installed remotely from the motor valve (see Motor Valves shown in Sections E1 and E2). This pilot is used for maintaining a constant pressure drop across meter systems or to produce a pneumatic output signal when the differential pressure of a system falls below the set differential pressure. (see Motor Valves shown in Section B)


SUPPLY PRESSURE: 0-300 psig, (60% or more of upstream pressure recom-mended for operating motor valves.)


OPERATION: The Pilot Assembly, which moves as a unit without friction within the housing, is supported by the PILOT DIAPHRAGM and the MODULATING DIAPHRAGM. The PILOT SPRING and Downstream Pressure (Blue) loads the upper side of the Pilot Assembly and is opposed on the underside by the Upstream Pressure (Red) acting on the PILOT and MODULATING DIAPHRAGMS (Area of PILOT DIAPHRAGM minus area of MODULATING DIAPHRAGM). The 12 PG PD Pilot can be considered as an inverse mul-tiplier. Each 1 psig change in Differential pressure, Upstream Pressure (Red) minus Downstream Pressure (Blue),results in a change in Output Pressure (Yellow) of 12 psig. The 30 PG PD-D/-S Pilot changes at a rate of 8:1. With a slight decrease in Upstream Pressure (Red) or a slight increase in Downstream Pressure (Blue) the PILOT ASSEMBLY is forced downward by the PILOT SPRING. The lower seat for the PILOT PLUG (Yellow to Atmosphere) is closed and the upper seat for the PILOT PLUG (Red to Yellow) is opened. This results in an increased Output Pressure (Yellow) under the MODULATING DIAPHRAGM which opposes the change. The PILOT ASSEMBLY returns to a position at which both the upper and lower seats are closed when the Differential Pressure is re-established. A slight increase in Upstream Pressure (Red) or slight decrease in Downstream Pressure (Blue) closes the upper seat and opens the lower seat to reduce the Output Pressure (Yellow).

100, 200 & 400 PDC

www.kimray.com

APPLICATIONS: The PDC Series Pressure Differential Controller connects across the orifice plate of a meter run to maintain a constant sta-ble pressure differential across the meter run. This relates to a constant flow rate when the upstream pressure is constant. This pilot adjusts the flow rate to maintain the pressure differential by positioning a pressure opening motor valve that has character-ized equal percentage valve trim for precise flow control. Precise gas flow rate for gas lift. Pressure differential control across orifice plates for better charts and measurement of gas flow. Stabilizes gas flow for better well production. Pressure differential limiting for reducing off chart condi-tions. Any applications where a constant pressure differential and flow rate is desired.

FEATURES: Intermittent bleed pilot Throttle operation 1 to 260 inches of water differential pressure Heavier springs available, if specified May be used with any type of diaphragm motor valve

WORKING PRESSURE: 1000, 2000 or 4000 psig maximum


OUTPUT PRESSURE: Variable, 2 to 30 psig

OPERATION: A typical system installation of the PDC Pilot consists of a PDC Pilot mounted so that the pressure differential across an orifice plate is applied across the diaphragm. The output sig-nal from the PDC Pilot operates a diaphragm control valve to maintain the desired pressure differential across the orifice plate (Two stage, filtered, regulation of instrument gas with drip pot or equivalent is recommended). Assume the control valve is open, and the pressure differential is rising. The Upstream Pressure is opposed by the Downstream Pressure plus an adjustable spring load. As the pressure differ-ential increases to the set point, there is an upward movement of the diaphragm assembly which is transmitted by the WAGGLE ARM causing a downward movement in the 3 PTC PILOT. The 3 PTC is now in a relief mode which allows the pressure opening motor valve to begin to close. As the valve closes, the pressure differential will decrease and reposition the PDC diaphragm assembly to stop the relief of motor valve diaphragm pressure.

If the pressure differential decreases from the set point, the spring forces the diaphragm assembly downward. This causes an upward movement of the WAGGLE ARM on the 3 PTC PILOT, increasing the diaphragm pressure of the pressure open-ing motor valve. As the valve opens, the pressure differential will begin to increase until it reaches the set point.

START-UP PROCEDURE:1. Open the isolation valves and close the equalizing valve (if

used) prior to applying pressure to the meter run to prevent an excessive pressure drop across the diaphragm. Excessive pressure drops across diaphragm will cause the diaphragm to rupture.

2. Turn the control knob fully counterclockwise.3. Open the gas stream to the meter run.4. Adjust the control knob until the motor valve begins to open.5. Continue to adjust the control knob until the desired pres-

sure differential is obtained. If the valve is fully open and the pressure differential is not obtained, recheck flow conditions,

pressure, valve sizing and orifice sizing.6. If the valve hunts (moves open and closed excessively), close

the needle valve in thee motor valve supply gas line until the positioning becomes stable or replace the motor valve trim with a smaller inner valve.

7. The Controller can now be set for the maximum limit or adjusted to control the desired pressure differential.

SIZING, INSTALLATION INSTRUCTIONS:1. Locate the motor valve conveniently upstream or downstream

of the meter run.2. Size and install the proper orifice plate for flow conditions.

Determine the pressure differential set point desired and install the proper spring for the maximum pressure differential to be controlled. (See Fig. 3)

3. The control valve should be sized according to recommended valve sizing procedures using equal percentage characteristic trim for precise flow control. Refer to gas rate charts for valve trim in the Kimray Catalog.

4. A metering valve or adjustable orifice can be installed to take

part of the pressure drop to provide better control conditions for the valve.

5. Mount the controller so that it is accessible and level. Connect the 1" connector upstream of the orifice plate and the 1/4" NPT connector downstream. Install isolation valve manifold if desired.

6. Connect a dry instrument gas source (20-30 psig) to the pilot supply and connect the control tubing to the valve. A needle valve on this line is sometimes helpful in stabilizing the motor valve / controller system. (See Fig.1)

LIQUID DIFFERENTIAL PRESSURE PILOT

APPLICATION: The 30 PG LDP-D sends a pneumatic signal when the differ-ential pressure between two wet or dry pressures is less the the desired setting. The signal vents when the difference is higher than the setting. Pilot may be installed remotely to operate a diaphragm oper-ated motor valve as a liquid differential pressure regulator.

FEATURES: Single adjustment Filtered gas supply Accurate control Intermittent bleed pilot Remote installation


SUPPLY PRESSURE: 0-300 psig (60% or more of upstream pressure recommend-ed for operating a motor valve)

OPERATION: The LDP Pilot consists of a PILOT DIAPHRAGM ASSEMBLY which moves without friction to operate a 3 way PILOT PLUG. The Pilot Assembly is supported by the PILOT DIAPHRAGM ASSEMBLY and the MODULATING DIAPHRAGM. The PILOT SPRING and Downstream Pressure (Blue) load the upper side of the Pilot Assembly and is opposed on the underside by the Upstream Pressure (Red) acting on the PILOT DIAPHRAGM ASSEMBLY. With a slight increase in Downstream Pressure (Blue) or a slight decrease in Upstream Pressure (Red), the PILOT DIAPHRAGM ASSEMBLY is forced downward by the PILOT SPRING. The upper seat for the PILOT PLUG (Yellow to Atmosphere) is closed and the lower seat for the PILOT PLUG (Violet to Yellow) is opened. This results in an increased Output Pressure (Yellow) under the MODULATING DIAPHRAGM which opposes the change. The PILOT DIAPHRAGM ASSEMBLY returns to a position at which both the upper and lower seats are closed when the Differential Pressure is re-established. A slight decrease in Downstream Pressure (Blue) or a slight increase in Upstream Pressure (Red) closes the lower seat and opens the upper seat to reduce the Output Pressure (Yellow).

12 PL FLOATLESS LEVEL CONTROLLER

www.kimray.comCurrent Revision:Move from Section F

APPLICATIONS: Oil and gas separator liquid level control. High level shut-off control. For use with Kimray MT series valves or Pressure Closing Motor Valves which use full separator pressure on the motor valve diaphragm.

FEATURES: No float required Easily installed Intermittent bleed pilot saves gas Throttling or semi-snap control Only one adjustment for changing control Only one adjustment for changing liquid level

WORKING PRESSURE: 175 psig maximumSUPPLY PRESSURE: Separate external supply not required. Pilot uses separator gas equalizing and supply line for supply.

OUTPUT PRESSURE: Varies from 0 psig to full separator pressure.

OPERATION: The Pilot Assembly (Crosshatched) and the PILOT PLUG are the only moving parts in the Liquid Level Pilot. The Pilot can be adjusted for throttling or semi-snap action using the CONTROL KNOB. With the CONTROL KNOB against its stop, the Pilot will throttle. Unscrew the CONTROL KNOB one-half to one full turn for semi-snap action. The PILOT PLUG consists of two stainless balls rigidly con-nected together. The upper seat for the PILOT PLUG controls Separator Pressure to Modulated Pressure (Red to Yellow). The lower seat for the PILOT PLUG is the Modulated Pressure vent (Yellow to Atmosphere). Separator Gas Pressure (Red) is equalized across the PILOT DIAPHRAGM. Separator Gas Pressure (Red) and the Modulated Pressure (Yellow) act in opposite directions on the two small diaphragms of equal area to balance the Pilot against changes in these pressures. The only upward force to move the Pilot Assembly is the liquid head in the separator, opposed by the PILOT SPRING. This spring load can be varied by the ADJUSTING SCREW to increase or decrease the liquid level. As the liquid level rises in the separator, it overcomes the PILOT SPRING and forces the Pilot Assembly upward, clos-ing the upper seat (Red to Yellow) and opening the lower seat (Yellow to Atmosphere). When the Modulated Pressure (Yellow) is vented, Separator Fluid Pressure then opens the valve. As the liquid level decreases in the separator, the Pilot Assembly moves downward closing the lower seat (Yellow to Atmosphere) and opening the upper seat (Red to Yellow), which increases Modulated Pressure and closes the valve. When the Pilot is adjusted for throttling, the intermittent bleed pilot three-way valve action of the PILOT PLUG against its seats adjusts the Modulated Pressure (Yellow) to reposition the Motor Valve Diaphragm to accommodate the required rated of flow. This rapid but stable repositioning produces a true throttling action. For standard separator service a light spring is installed in the Pilot for a maximum liquid level height of approximately 4 feet. For other service, special springs can be installed for a maximum liquid level height of either 8 or 30 feet. Unless otherwise speci-fied, a light spring will be furnished.

PILOT DIMENSIONS

TYPICAL INSTALLATIONINSTALLATION: 1. Install the Motor Valve in the separator oil outlet line. 2. Install Drip Pot on 12 PL, separator gas line. 3. Mount the 12 PL Pilot on the separator shell in the liquid section. For best operation, the pilot should be located at least 4 inches below the minimum desired liquid level. 4. Connect Gas Equalizing and Pilot Supply Line between the Drip Pot and the gas section of the separator with 5/16 inch tubing and fittings. CARE should be taken so that the equalizing gas is as dry as possible. The equalizing gas must be the SAME pressure as the that in the liquid section. DO NOT connect to the gas outlet line or downstream from mist extractors. 5. Connect pilot output pressure to Motor Valve with 1/4 inch tubing and fittings as shown.

NOTES: The lower gauge glass connection may be used for mounting the pilot if no other connection to the liquid section of the separa-tor is available. A connection is provided on the upstream side of the motor valve body for mounting the pilot. However, when the Motor Valve is set remotely from the separator, pressure drop through long piping will make the controller operation erratic. After assembly, the pilot is tested and set for throttling control. It is adjusted to control a liquid level of approximately 7 inches above the pilot, turn the adjusting screw for desired liquid level. On throttle control, the liquid level will vary approximately 1 inch. When set on semi-snap control, the liquid level will vary between 4 inches and 8 inches.

SENSE LINE PROTECTOR

www.kimray.com

APPLICATIONS: As an adjustable, self-resetting, pressure limiting device to protect instrumentation from over pressurization and subsequent damage. Designed to protect pilots on high pressure regulators. Blocks the sense line or supply pressure to a device when it exceeds the adjustable limit of 300 psig. Reopens when inlet pressure drops below the limit.

NOTE: This device is not to be installed as a: Instrument gas regulator, Pressure reducing regulator.

CONNECTIONS: Inlet and Outlet - 1/4 NPT

DESIGN PRESSURE: 1000 psig. Max.

OUTPUT PRESSURE: 0 to 300 psig

FEATURES: Single Adjustment Intermittent bleed pilot Remote Installation Compact Design

OPERATION: The Pilot Spring loads the upper side of the Pilot Diaphragm Assembly and is opposed on the under side by Output Pressure (Blue) acting on the area of the Pilot Diaphragm. As long as the Input Pressure (Red) is below the setting for the desired maximum Output Pressure (Blue) the Pilot Diaphragm Assembly is held down by the Pilot Spring, and the lower seat of the Pilot Assembly (Red to Blue) is held open, allowing direct communica-tion of input Pressure (Red) to Output Pressure (Blue). Changes in the Input Pressure (Red) will directly result in changes in the Output Pressure (Blue) unless the pressure reaches the upper limit established by the setting of the Pilot Spring. At this point the Pilot Diaphragm Assembly is forced upward to the point the lower seat for the Pilot Plug (Red to Blue) is closed, preventing any further increases in Output Pressure (Blue). If for any reason conditions would cause the Output Pressure (Blue) to start to increase above the desired set point, the Pilot Diaphragm Assembly will move upward, opening the upper Pilot Plug Seat (Blue to Atmosphere) and relieving enough pressure to restore Output Pressure (Blue) to the set point. When the Input Pressure (Red) returns to a level below the set point limit, the Pilot Plug will drop slightly allowing Input Pressure (Red) to again communicate with Output Pressure (Blue). The upper limit for the Output Pressure (Blue) is set with the adjusting screw. Turning the Adjusting Screw clockwise will increase the Output Pressure (Blue) limit, turning the Adjusting Screw counter clockwise will lower the Output Pressure (Blue) limit. The maximum output pressure is 300 psig.
